You can't as they are not supported See here (Orion) and here (Prisoner) There are out-of-tree engines available, but i don't know the state of them. Maybe someone else knows more. In summary: You can't play games just because you have the data files, this is not DosBox, it needs a dedicated person ...

Add a new suffix ".zip" to your save file and attach it.

Does something like this exists?

Ingame gfx work fine with shaders, but especially early "real life" movies woven into games have aged poorly.

Could those be enhanced too?

Thank you

Accolades "Altered Destiny" and "Les Manley"? *puppy eyes*

@adventurefan I see, seems the wiki entries were merged losing the difference in both games needed files...unfortunate again :-) Chess.xxx is used only by Serrated Scalpel, btw Here are my file lists for both games (i tend to keep all the files there, not sure which aren't needed) Rose Tattoo ADLIB....

@adventurefan If you follow the link from the wiki entries to the user manual you'll find this paragraph For games on floppies or CDs, if the data files are accessible, the external media can be accessed directly by ScummVM.

Hmm, it would probably be best to report it on the bug tracker

Could you post a Screenshot?

I suspect the switch to the lr-scummvm solution, together with the update, messed up your settings

You still got your data files, I assume?
I'd suggest reinstalling scummvm and sticking with one of the, obviously not compatible, solutions.

lr-scummvm works differently from "normal" scummvm.

They have different ways the loader use the games files (for scummv it needs .svm text files created which it reads from the main directory, lr-scummvm however directly reads the files from inside the game folders themselves)

Have you tried going back to 2.6?

Understood, thank you

Done
